如何修复错误消息：'chromedriver.exe' 可执行文件可能具有错误的权限

Question

我正在安装 selenium 的 webdriver。但是我收到以下错误：

PermissionError                           Traceback (most recent call last)

   1345                 raise child_exception_type(err_msg)

PermissionError: [Errno 13] Permission denied: '/usr/bin/chromedriver.exe'

During handling of the above exception, another exception occurred:

我已下载 chromedriver.exe 并将其添加到 /usr/bin，代码行如下：!sudo mv /usr/local/bin/chromedriver.exe /usr/bin

你不能解决我代码的错误吗？提前致谢！

可能是因为平台和 chromedriver 格式不匹配。例如 windows 需要 chromedriver.exe，而 linux 和 mac 有不同的格式。如果您不想通过包管理器安装，只需从站点下载 chromedriver。 https://sites.google.com/a/chromium.org/chromedriver/downloads

如果仍然出现错误，则转到 /usr/bin 目录，您需要运行类似 chmod a+x chromedriver 的内容来将其标记为可执行文件。
